A54SX32A-TQ144I

The A54SX32A-TQ144I is a nonvolatile SX-A family FPGA provided in a 144-pin surface-mount package. Designed for industrial-grade applications, this device delivers a mid-range programmable logic capacity with mixed-voltage I/O support and family-level performance characteristics drawn from the SX-A series.

Key value propositions include single-chip nonvolatile configuration, configurable I/O for multiple supply domains, and deterministic timing and test features that simplify board-level integration and verification for industrial and mixed-voltage designs.

Key Features

• Logic Capacity — 48,000 system gates and 2,880 logic elements (logic cells) provide mid-range programmable logic for control, glue logic, and protocol bridging tasks.
• User I/O — 113 user-programmable I/O pins allow flexible interfacing to external devices and buses while supporting multiple voltage domains.
• Nonvolatile Single-Chip Configuration — SX-A family nonvolatile architecture removes the need for external configuration memory, simplifying system BOM and power-up behavior.
• Family Performance — SX-A family performance characteristics include up to 250 MHz system performance and up to 350 MHz internal performance (family-level specification).
• Configurable I/O and Mixed-Voltage Support — I/O supports 5 V TTL/PCI, 3.3 V LVTTL, 2.5 V LVCMOS2 and mixed-voltage operation; devices in the family support 5 V input tolerance and 5 V drive strength where applicable.
• Power and I/O Robustness — Hot-swap compliant I/Os and power-up/power-down friendly operation (no sequencing required for supply voltages) ease integration into live-insertion and multi-rail systems.
• System Test and Security — Boundary-scan (IEEE 1149.1 JTAG) for board-level testability and Actel Secure Programming Technology (FuseLock™) to protect intellectual property and prevent reverse engineering.
• Package and Mounting — Surface mount device in a 144-pin package. Product data references Package Case: 144-LQFP and Supplier Device Package: 144-TQFP (20 × 20).
• Industrial Temperature Grade — Rated for operation from −40 °C to +85 °C for industrial applications.
• Voltage Supply Range — Operates across a wide supply range from 2.25 V to 5.25 V for flexible system integration.

Typical Applications

• PCI and Bus Interface Logic — Family support for 66 MHz PCI and configurable I/O levels makes this device suited to bus interfacing, protocol bridging, and glue-logic roles.
• Board-Level Test and Production — Boundary-scan (IEEE 1149.1) support simplifies in-circuit testing and production test flows.
• Industrial Control and Mixed-Voltage Systems — Industrial temperature rating plus mixed-voltage I/O support enable deployment in industrial controllers and equipment that interface with multiple voltage domains.
• Secure Embedded Functions — Nonvolatile single-chip configuration and FuseLock™ security are appropriate for designs requiring on-board configuration retention and IP protection.

Unique Advantages

• Single‑chip, nonvolatile configuration: Eliminates external configuration memory and simplifies system start-up and maintenance.
• Flexible mixed-voltage I/O: Configurable I/O standards and 5 V tolerance options enable straightforward interfacing to legacy and modern signaling levels.
• Industrial-grade operation: −40 °C to +85 °C rating supports deployment in industrial environments.
• Board-test friendliness: IEEE 1149.1 boundary-scan and deterministic timing aid debugging, production test, and system verification.
• IP protection: Built-in FuseLock™ secure programming technology reduces risk of reverse engineering and protects design IP.
• Compact surface-mount package: 144-pin TQFP/LQFP-class package supports high-density PCB layouts and automated SMT assembly.
